17.4.2 Engine High Speed Governor Configuration
The high speed governor run out line gradient can be configured using the
service tool and the mode selection feature as described in section 17.5 of
this document. This is achieved by modifying RS or HI or both. It should be
noted that HI cannot be configured to be less than RS and no higher than RS
+ 12%.
17.5 Mode Selection
17.5.1 Mode Selection Operation
A mode is a performance characteristic in terms of power / torque, droop,
speed governing and rated speed. There are up to four modes configurable
for the Perkins Tier 4 product range. These modes are selectable during
normal engine operation while the engine is running and on load apart from
when a speed governing change is required.
Two ECM J1 switched inputs are provided for this feature and each switch
combination can be configured to provide a separate mode configuration.
Examples of the selectable modes are shown below.
• Engine % Droop
• Engine T Curve Rating (If multi ratings are enabled)
• Engine rated speed (Only if the rating supports multiple rated speeds)
• Engine speed governing mode (Min / Max or All Speed)
